First, thanks Len for the heads.
Here's a report from my 914 Chump car.
I did a test day on September 7th. I did four sessions with about 6-8 laps each at Sebring. While on track I get a chance to look down at my cylinder temp gauge between turn 16-17. I never seen it over 350 degrees. It stabilized after about two laps. Oil temp does too. It was hot at the track and my third and fourth session I ran it pretty hard. Still never seen above 350 degrees.
Heres some stuff I can tell you about the heads.
The work from Len was great. He could elaborate on all he did.
Heres what I can tell you all.
He coated in the chambers
He notched cylinder head 3 plug for the cylinder head sensor (awesome)
He put some special magic black coating on the heads for heat
He twisted my arm and made me run ti retainers (for when someone misses a shift!)
The heads are not leaking oil from the pushrod tubes.
The spark plug placement was correct for my 2.0 liter tin
I'm hitting the dyno in a few weeks and I think I should be at 155-160hp.
I'll report back when thats done.
